```Hi!

There is a symbol that I don't know how to write it in Tex/laTex .I saw lots os documents, websites, and none of them show this symbol.

It is a triangle made of 3 points, instead of lines. In a logic expression, it is used to give us the result.
For exemplo if \exists ... therefore ...

How can I write this symbol?

Thank you,Alexandre.
